A correlation search is a scheduled search that runs periodically to detect patterns of interest in the data and generate notable events or other actions when the search conditions are met. A correlation search can generate false positives, which are notable events that do not represent a real security incident or threat. False positives can create noise and reduce the efficiency and accuracy of the security analysis. To reduce false positives from a correlation search, you can modify the correlation schedule and sensitivity for your site. The correlation schedule determines how often the correlation search runs and over what time range. The sensitivity determines the threshold or limit for the search conditions to trigger a notable event. By adjusting the correlation schedule and sensitivity, you can fine-tune the correlation search to match your environment and data sources, and avoid generating notable events for normal or benign activities. You can modify the correlation schedule and sensitivity for a correlation search using the Content Management page in Splunk Enterprise Security. References =
